244) An Experimental Study on Cylindrical Concrete Shells subjected to Horizontal Force(Civil Engineering)

The study of WJ-8 rail fastening is about the relationship between lateral horizontal force and rail’s lateral displacement, and the rail fastening’s transverse stiffness was obtained since the rail slipped. The rail lateral displacement was measured by using the loading device of rail’s lateral horizontal force which was changed as needed. Moreover, when the lateral horizontal force changes, it was analyzed that how it affected rail’s lateral displacement and rail fastening’s transverse stiffness under different bolt torque conditions. Therefore, the recommended value of transverse stiffness is acquired which is based on analyzing the test results.

Temperature Position

Fire resistant behavior is one the main properties of shield tunnel segment in civil engineering. The main objective is to study the regularity of temperature distribution and deflection of shield tunnel segment after fire and the residual bearing capacity after cooling in this paper. According to the tests, a temperature-position fitting curve can be obtained, and it can be obtained that the damaged depth of segment is 7.8cm while heating in RABT curve for 125min. It is found that the residual bearing capacity of segment decrease with the increase of the pre-load, which drops rapidly for it is only about 20% compared to the reference one.

The force of ship is one of the main loads which High-Piled Wharf bears, the assignation of transverse component on each bent is the precondition of the calculation which simplified the wharf structure into plane bent. The taking value of transverse component on bent influences a lot on the result of structure calculation. Nowadays, the design of High-Piled Wharf uses the value from the distribution coefficient in the Design and Construction Code of High –Piled Wharf. The results show that the distribution coefficient taken in the code is under the precondition that considering the beam is rigid; the relative stiffness of beam and pile can influence this distribution coefficient. Considering the flexibility of the beam, the distribution coefficient of the horizontal concentrated force on transverse bents will change.
